Abstract
Abstract An ultrasonic wire bonding method that uses an ultrasonic oscillation output from a non-rotatable form, wherein the ultrasonic oscillation output used for bonding the leads that extend in an X-direction which is perpendicular to the axial direction of a horn is set to be larger than the ultrasonic oscillation output used for bonding the leads extending in a Y-direction which coincides with the axial direction of the horn.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
90 words
An ultrasonic wire bonding method in which bonding is performed by an ultrasonic vibration applied to a capillary via an ultrasonic oscillation output which is outputted from a horn that is not rotatable, said method being characterized in that bonding to .leads extending in an X direction which is perpendicular to an axial direction of said horn is performed by an ultrasonic oscillation output which is larger than an ultrasonic oscillation output used for bonding leads extending in a Y direction which coincides with the axial direction of said horn.
Claim 2
Dependent Claim
90 words
An ultrasonic wire bonding method in which bonding is performed by an ultrasonic vibration applied to a capillary via an ultrasonic oscillation output which is outputted from a horn that is not rotatable, said method being characterized in that bonding to .leads extending in an X direction which is perpendicular to an axial direction of said horn is performed by an ultrasonic oscillation output which is larger than an ultrasonic oscillation output used for bonding leads extending in a Y direction which coincides with the axial direction of said horn.
Claim 3
Dependent Claim
38 words
An ultrasonic wire bonding method according to claim 1 characterized in that said ultrasonic oscillation output is automatically calculated from a bonding angle of a lead and a correction range in which said ultrasonic oscillation output is corrected.
